Troubleshooting

Below is a list of image/explanation pairs which describe frequent sources of problems with Selenium- IDE:

This problem occurs occasionally when Selenium IDE is first brought up. The solution is to close and reopen Selenium IDE. The bug has been filed as SIDE-230.

You’ve used File=>Open to try to open a test suite file. Use File=>Open Test Suite instead.

This type of error may indicate a timing problem, i.e., the element specified by a locator in your command wasn’t fully loaded when the command was executed. Try putting a pause 5000 before the command to determine whether the problem is indeed related to timing. If so, investigate using an appropriate waitFor* or *AndWait command immediately before the failing command.

Whenever your attempt to use variable substitution fails as is the case for the open command above, it indicates that you haven’t actually created the variable whose value you’re trying to access. This is sometimes due to putting the variable in the Value field when it should be in the Target field or vice versa. In the example above, the two parameters for the store command have been erroneously placed in the reverse order of what is required. For any Selenese command, the first required parameter must go in the Target field, and the second required parameter (if one exists) must go in the Value field.

One of the test cases in your test suite cannot be found. Make sure that the test case is indeed located where the test suite indicates it is located. Also, make sure that your actual test case files have the .html extension both in their filenames, and in the test suite file where they are referenced.

Selenium-IDE is very space-sensitive! An extra space before or after a command will cause it to be unrecognizable.

Your extension file’s contents have not been read by Selenium-IDE. Be sure you have specified the proper pathname to the extensions file via Options=>Options=>General in the Selenium Core extensions field. Also, Selenium-IDE must be restarted after any change to either an extensions file or to the contents of the Selenium Core extensions field.

This type of error message makes it appear that Selenium-IDE has generated a failure where there is none. However, Selenium-IDE is correct that the actual value does not match the value specified in such test cases. The problem is that the log file error messages collapse a series of two or more spaces into a single space, which is confusing. In the example above, note that the parameter for verifyTitle has two spaces between the words “System” and “Division.” The page’s actual title has only one space between these words. Thus, Selenium-IDE is correct to generate an error.
